#ct-elfe 'that the following is a full, clear, andexect description thereof, reference Abeingfiied tothe accompanying drawings, which -formpart of this'specification;Y y

. This invent-ion` is anovcl improvementin .grease cups and' it comprises a'draWn metal cup ofnovel construction; a drawn metal Vplunger and stem' ot" novel const-rue* tion; land a drawn nietely handle of novel .construction;-1 Its objectsere to produce an all-drawn metal cup which will possess all tte advantages of the best of grease cups now in use out will be more eiicicntand contain more grease than' the present, cups of like size, and can be made cheaply and economically.

The body the cup may resemble any or dinary form of cup in its external appear4 ence. This body comprises a cylindric portion A. having a contracted bottom connected' with e contracted hexagonal portion B; and creow this is a still further contracted eX- teriorly threaded. portion C, all these are formed integral of drawn metal. The portion C is closed at the' bott-ein, save for :1. minute. aperture c for the escape of grease. hexagonal portion B forms a convenient ineens for applying a Wrench when securing` the. cup in position.

The upper end of the body A is forced T 'eclr or swt/aged into a thickened portion as shown a.. thus forming a double thickness ai et the top of the cup, and this part erneily threaded, as shown, for the geg-rement of a cover D; and it isalso interxxelly threaded, as shown, for the'engagenient of e plunger E. This thickening of the end of the cxup as et a; is en irnportant texture of the invention, es it ensbles us to provide an externally threaded portion and an internally threaded portion xthrendson part (tot the I i 'entends through a' .suxtnbefopeningin' its" upper end.

The upper end of the stern i" is contracted or flattened, by pressure, as shown at f, so that it can be entered into the slot g, and it is then headed or riveted over ns shown at f to secure the handle thereto. The. piece G is then bent by suitable tools into circular torno, and its ends contracted, thereby closing .it so as to round the ends of the handle neatly :is shown in Fig. l. The advantages of this construction are the great simplicity `with ivhich the parts can be drown fromsuitable metal; the lightness of the cup; `its strength; and the greatly increased grease capacity comp-ered with-castinetal cups.

lThe stein i? being hollow also greatly increases the ln'llffiing'cnpacity oit the cup and ns the i'iloitity of the part to winch the cnp is attached becoming overheeted for weint of grease, as this hollenv stern i? willv till with grease which will ordinarily remain therein, but it the grease lin the body of the cup should become exhausted and the parts begin to lient, the grease in the stein willY melt and lubricate the bearings or "f'rtsz The hollow stern F thus forms en nary or safety grease' reservoir which is e peculiar and very' useful feature of 'the present invention.

what we claim is: l. A drawn metal grease cup comprising a oe-dy portion haring its 'upper end thickl :g the metal upon itset,

\ tracted hexagonal portion below the upper portion and a further reduced cylindric portii below the hexagonal ortion all formed integral of drawn metal, t e upper cylindric portion having its upper end thickened by swaging the' metal upon itself and threaded internally for engagement of a plunger,and the thickened portion being threaded externally tor the engagement of a cap, and the lower cylindric portion having its end closed but provided with an aperture for the escape of grease and threaded externally; with a drawn metal plunger having an externally threaded ange engaging the interior threads of the upper portion, and an integral hollow stem integral With the plunger, and a cap through which the stem passes fitted to the top of the body portion.V

3. In combination an internally threaded grease etgp; a drawn metal plunger comprisying a hollow st'em and a disk integral With the stem having a flange on, its periphery integral therewith and exteriorly threaded to engage the cup; the upper edof the stem being contracted; a handle attached to the upper end of the stem, and a cover attached to the upper end of the cup.

4. A grease cup comprising an internally threaded body of drawn metal, a drawn metal plunger therein comprising a hollow Stem, and a disk integral with the stem having an extcriorly threaded flange, on its periphery, the upper endof'the stein being contracted, and a handle attached to the upper end of the stem and comprising a plate having foliated ends, the plate being bent in cylindric form and the foliated ends closed against themselves to close the ends of the handle.

In testimony that we claim the foregoing as our own,` We alix our signatures in presence of two witnesses.
